GNS 530 - "Navigation Data License Invalid"

Featured Replies

After cloning my system disk last night on my simulator (I ran out of disk space on the old drive), my GNS 530 won't work, displaying only the message 'Navigation Data License is Invalid" (or something close to that).  I have a current subscription for quarterly updates of RealNav data.

Did I mess something up by cloning my old drive to a new one?
